Anthony Lawler, portfolio manager at GAM, says: "Policy uncertainty on both sides of the Atlantic was arguably a dominant factor influencing global markets in October. Investors and corporates remain hesitant to invest and hire when the policy, tax and regulatory framework is in flux. Europe is debating its way toward a hoped 'muddle through' solution. However, there are still numerous country-specific hurdles to clear. In the US, investors face the dual uncertainties of the election and the fiscal cliff. Given these unknowns, they generally remained cautious or de-risked their portfolios by selling during October. Notably even sovereign bonds, that are commonly perceived as safe havens, sold off with UK gilts, US treasuries and German bunds all producing negative price moves for the month."

October was a challenging month for many managers and this included trend following CTAs. These managers in aggregate held portfolio positions that typically act balanced, as they were positioned long bonds, a bearish bet, against long equities and long energy, bullish bets. In October all three of these positions moved together and resulted in a negative month for CTAs.

Lawler says: "A number of hedge fund managers across strategies turned more positive after the Fed's QE3 announcement in September. In October, these managers' more bullish views proved generally unhelpful for those long risk assets outside of structured credit. But constructive and risk-on positioning did continue to help managers of structured credit positions and some relative value managers, where we continue to see solid out-performance. That said, at the end of October many hedge funds have slightly reduced risk going into the US election, but they stand ready to add risk back on once a clear result emerges."
